For specific architectures look at the following directories. 386 family version: ftp://ftp.freebsd.org/pub/FreeBSD/FreeBSD-stable/src/sys/i386/i386/in_cksum. c Alpha version: ftp://ftp.freebsd.org/pub/FreeBSD/FreeBSD-stable/src/sys/alpha/alpha/in_cksu m.c If you are looking at checksum functions for a wide variety of architectures like arm, powerpc,mips, hp etc, netbsd source code repository is a good source. Use the same directory structure as above to get those. ----- Original Message ----- From: "Kshitij Gunjikar" To: Sent: Saturday, January 12, 2002 6:59 AM Subject: Performance of in_cksum.c > Hi , > I have a question on the in_cksum.c file.
